I have shown one form of my improved road.

chair used in assembling an upper series of intersecting reeniorcmgrodsA and B and a lower series of intersecting reenforcing rods Myimproved road chair is formed from a single continuous piece of heavywire and comprises a single lower upright portion 20, an intermediateofiset portion 2l and a second upright portion 22 bent atitsfupperf'encl to provide a loop '23 overlying the upper 'rod Aof theupper series,'a transverse loop '24 underlying the lower rod'B oftheupper se-,

ries andan end'projection 25 also overlying therodA. 7

- The lower end of theupright portionis bent to provide a horizontalloop 26 and at the free end of the loopthe wire isinclined upwardly: andoutwardly as indicated at 27 and is providedwith an offset endportion orhook 28 adapted to overly the lower rod -B of the lower series. 1.

The chairs are assembled as indicated in Fig. 1, with the lower'rod B ofthe lowerseries resting on the ofi'set portion 21, the upper rod A ofthe lower series supported on the rod B, the-lower rod B of the upperseries supported in the loop 24 and theupper rod A of. the upper seriesresting on the rod B and held from-upward displacement by the loop 23and end portion 25. i

The offset lower'end portion 28 overlies the lower rod B of the lowerseries and prevents clockwise angular movement of the chair relative tothe rods B and B as viewed in Fig. 3. The offset .end'28 also assists inholdingthe rod B in position At the same time the loop 24 underlying thelower rod B of the upper series and the loop 23 and end portionoverlying the. upper rod A of the upper series prevent anti-clockwiseswinging movement of the chair relative to the rods movements in eitherdirection.

B and Bf and also prevent lateraltwisting.

and they definitely space and position the two series of rods relativeto each other and to a supporting surface, the loops 26 formingsubstantial and extended footings for the road chairs.

In order to retain the transverse rod A of the lower series in positionon the longitudinal rod B, I provide the retaining clip 30 shown indetail in Figs. 4, 5 and 6. The clip 30 comprises a piece of wireextended at right angles to the upper. rod to be secured and providedwith an offset portion or hook 31 at its end adapted to hook under thelower rod of the pair to which the clip is applied. The wire 30 isoffset upwardly at 32 to overlie'the rod A and is then doubled and bentdownwardly to provide a U-shaped loop 33,

y the extreme lower portion of which is bent forward in the form of aU-shaped projection 34. This projection 34 is preferably curved toclosely engage the offset portion of the chair.

The short side of the loop 33 is curved and bent forwardly, as indicatedat 35. substantially parallel to the portion 30. The down-.

wardly bent portions 33 converge, as indicated in Fig. 6, and are sospaced that the rod B will be engaged and held against the lower side ofthe rod .A andsubstantiallv above the projection 34. I.

When in use, the retaining clip is applied as indicated in Fig. 1. withthe projection 34 underlying and gripping the offset portion 21 of theroad chair. The clip -is therefore effective not only to secure the rodsA and B together. but also to secure the lower pair of rods to theoifset portion 21 and thus prevent upward displacement of the rods. 'Theclip also secures the rods to the upright portion 22 and preventslateral displacement.

My improved road chair and cl-ip'are both formed from a minimum amountof material'to accomplish the designated purposes and they provide rigidand substantial support for an upper and lower series of reenforcing'rods as already fully described. The various rods are so firmly securedtogether that a mat formed of rods secured by my improved chairs andclips may be lifted and transported as a unit from the assemblingrack-to the road position in which it is tobe used without collapsing orfolding inany direction. V

v While I have shown the free end of the loop 26 extended upwardly at 27and offset at 28 to overlie the lower rod B and thus prevent rocking ofthe chair clockwise, I may accomplish the same purpose by extending theupper end 25 of the chair as indicated at 37 in Fig. 10 and providing anoffset portion or hook"38 adapted to underlie the up perrod B. Theextension 37 and-hook accomplish exactly the same'purpose as theextension 27 and offset or hook 28 and likewise prevent clockwiserocking of the chair.

It will be understood that the construction indicated in Fig. 10 may besubstituted for the construction shown in 27 and 28 in Fig. 2 or forsimilar constructions in the forms shown in Figs. 7, 8 and 9, and itwill be further understood that the parts 37' and, 38 may if desired beused in addition to the complete construction shown in the otherfigures, as indicated at the right in Fig. 1.

In Fig. 7 I have shown a form of road chair which in general closelyresembles the form previously described but in which the offset 41between the upright portions 40 and 42 is in line with the lower rod Band is inthe plane of the upper loop A3.

This construction may be used where it is desirable that the parallelrods A and A form the extreme upper and lower members of the assemblyand the parallel rods B and B form the intermediate members. The tieclip 30 is the same as previously described and serves the same purpose,exceptthat the end 31 thereof is hooked under the rod A instead of underthe rod B as in the previous construction.

In the construction shown in Fig. 8, an offset depending loop 51 isformed between the upright portions 50 and 52 and the foot portion 56 ispreferably (but not necessarily) exthis construction, a standard form ofretain ing clip 58 may be used by merely increasing its width. 7

'In Fig. 9, I have shown a modification of the construction shown inFig. 8, in which the extended loop or foot portion 56 is omitted and theinclined portion 59 is connected directly to the lower end of theportion 50. This somewhat simplifies the manufacture of the chair butcorrespondingly reduces the footing of the chair in: contact with theroad bed or other supporting surface. This con struction may besubstituted in the other forms also.

In all forms of the invention, the offset intermediate portion ispreferably curved downwardly to form a recess to more effectively retainthe r'eenforcing rod supported thereon.

All forms of my invention firmly support both'the upper and lower seriesof reenforcing rods in such a manner that the assembled structure cannotbe canted or collapsed by swinging movement of the chairs. The twoseries of rods are also supported and secured in such a way that theyare definitely spaced limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is 1. road chairformed from a single continuous piece of wire andcomprismg a singleupright member oifset: at an intermediate' upright member offset at anintermediate point to provide a support for, a lower pair of reenforcingrods and reversely bent and doubled at its upper end to position andsupport a second pair of reenforcing rods, one end of said uprightmember being extended laterally to engage one of said reenforcing rodsat a point substantially spaced from said upright member, therebypreventing rocking movement of said road chair relative to said rods inone direction.
